Hi. This is indeed a setting in xorg.conf, however, this part in the dmesg is
new:
[ 2.073595] [drm:drm_mode_debug_printmodeline [drm]] Modeline 63:"2560x1440"
60 241500 2560 2608 2640 2720 1440 1443 1448 1481 0x48 0x9
[ 2.073600] [drm:drm_mode_prune_invalid [drm]] Not using 2560x1440 mode:
CLOCK_HIGH
It seems to try and validate my modeline but discard it as invalid.
I will try and use xrandr right away.</pre>
